I just want to share a breakout board I've been working on for a couple of years. This is a takeoff/expansion of the octoWS2811 for the Teensy 4.1, that brings 32 pins out to the RJ45 sockets instead of the 8 available on the octo board. It also pulls out the ethernet onto the board for ethernet access. I designed this to run my christmas lights. It can also run a matrix, or any other WS2811 project. The code linked to below is specific for E1.31 data, but could easily be modified to receive commands via another method, such as USB, or from a file on an inserted SD card. Since the T4.1 has so much more built in capabilities than the other PJRC boards, especially with the onboard ethernet, I needed a breakout board that would access more of the power of this board than the octoWS2811 was capable of. This board is primarily an expansion of that awesome board. I want to thank everyone on the forum who has helped me get this working, and especially Paul for giving us all the awesome Teensy 4.1 board to play with.
The main improvements on the octoWS2811 board are:
The sync pin wasn't brought out, as I didn't need to sync multiple boards. The math says this board should support up to 32,000 pixels. In practice, I've only got it up to about 4,000.

I've made my prototype production extras available on tindie.com. If there is interest, I'll keep the store stocked.
